Why Biochar?
Biochar improves soil health, boosts microbial activity, retains nutrients, and locks away carbon for hundreds of years. Traditional methods of making it can be unsafe and polluting. Our kiln uses innovative clean-burn technology that safely converts wood smoke into heat, CO₂ and water vapour—no harmful emissions.
Thousands of gardeners are turning to biochar for more resilient, fertile soils—and you can make your own, right at home. The best way to use biochar is to blend it with finished compost, or to add it to your home composter and wait for the biochar amended compost to be produced. However, there are 55 uses of biochar, not just for soil, check out our podcast episode with Roots and All to hear about some of these fascinating uses.
